Protects the catalytic converter from clogging with soot. Cleans the injection system and the combustion chamber. The combustion improver works directly, which leads to an immediate, measurable reduction of the pollutants. Clean engines use less fuel and emit less CO2. Prevents corrosion in the fuel system. Tested for turbochargers and catalytic converters. Suitable for all gasoline engines with a catalytic converter. Particularly as a preventative measure. 300 ml is sufficient for up to 70 liters of fuel. Effect remains for up to 2,000 km.
